q3 i? For fifth graders, there was no effect of the self-explanation prompt contrast at posttest or follow-up. → Hänze 2022

Evidence¶

Hänze 2022¶

Hänze, M., & Leiss, D. (2022). Using heuristic worked examples to promote solving of reality-based tasks in mathematics in lower secondary school. Instructional Science. https://doi.org/10.1007/s11251-022-09583-8

q3 · i? · causal · r2

In the fifth-grade ANCOVAs, the contrast comparing prompted with unprompted worked examples was not significant at either measurement point; no effect size was printed for this contrast.

"There was no effect of Cprompts neither for post- test nor for follow up measurement."
